“A” and “B” materials flow through their individual delivery hoses. The two material hoses plus control air lines join the
main system to the dispensing applicator. The type of hose used will vary, and are specifically chosen for the application.
Any replacement must be identical or of superior specifications in terms of pressure, dimensional rigidity under pressure,
and porosity.
The hoses used have a teflon core with stainless steel braiding on the outside. They can be damaged if severely kinked,
but are generally resistant to most solvents that may be used to flush the system.

The applicator for the GMP-025 can be a manually actuated dispense applicator or an air actuated dispense valve. Please
review machine components to become familiar with the dispense assembly.
If a manually actuated dispense applicator, system operating (“on” and “off”) signals are given when the operator presses
the applicator switch.
“A” and “B” materials are kept separated to the point where they join together inside the disposable plastic mixer at the
applicator tip. A retaining nut forces a tight fit of the disposable mixer nozzle to the threaded applicator block.
Two grease zerks are located on the side of the dispense manifold. These can be used to fill the manifold with a
compatible lubricant to prevent material problems inside the manifold when not in use. Only lubricants compatible with the
material to be dispensed can be used. The same lubricant can be used in the pumps.
A check valve for each component is located inside the manifold. The check valves supplied are assemblies which should
be disassembled and cleaned periodically. The o-ring inside the check valve can be replaced, if necessary.

6. STATIC MIXER
Sometimes referred to as a “mixer nozzle,” the static mixer is a disposable tube that mixes parts “A” and “B” together as
they are pumped through the elements inside the tube. Mixers are available in a variety of diameters and mixing elements
(length). Field experience will determine which diameter, element quantity, and tip opening size is best. The first material
out of a static mixer should be discarded & not used, especially for materials that are not 1:1 ratio.
NOTE: When not in use, the static mixer should be removed and discarded. Attempting to use a static mixer that has become partially cured can
result in crossover, or one component being forced inside the manifold port for the other component.
